The newest acquisition for the PS3 is Guitar Hero-World Tour. After loading the game and putting the "instruments" together I decided to give the guitar a try. Some how I was able to strum my way through the first gig in career mode. Just as I was completing the gig my son and a friend arrived and wanted to get in on the action. So I was moved from guitar to singing. We rocked for about two hours straight. Lots of fun!
I highly recommend this one. Fun for all.
I've played a couple of times since. Twice with my son and his friends and once by myself. It is a good game to play with a group. Just as long as you don't mind getting made fun of when you stink up a song.
